[0031] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 7 As shown, a danger removal device for tunnel excavation accompanying operation includes a crawler chassis 1 and a top frame 2 with a concave structure, the top frame 2 is arranged on the top of the crawler chassis 1, and the top surface of the top frame 2 is arranged in an inclined surface, and a trimming mechanism 3 is arranged at one end of the top frame 2 near the opening;

[0033] The trimming mechanism 3 includes a vertical frame 31, which is fixedly mounted on the inner wall of the bottom of the top frame 2 near one side, and a long rod 32 is provided through the center of the front and rear ends of the vertical frame 31, and two sets of long rods 32 are rotatably connected to the ends away from each other with double-axis gear rollers 34, and the ends of the shafts of the two sets of double-axis gear rollers 34 near the long rods 32 are fixedly sleeved with main transmission wheels 35;

[0034] The trimming mechanism 3 also includes two sets of hollow sliding frames 36 movably arranged inside the top frame 2 and located at the front and rear ends. The two sets of hollow sliding frames 36 are rotatably connected to the main rotating gear disc 37 at the center of the side away from each other. The ends of the shafts of the two sets of double-axis gear rollers 34 away from the long rod 32 respectively penetrate the hollow sliding frames 36 and are fixedly connected to the center of the main rotating gear disc 37. The shaft sections of the double-axis gear rollers 34 extending from the hollow sliding frames 36 are provided with snap rings that are clamped at the inner and outer frame walls of the hollow sliding frames 36.

[0035] The surface of the hollow sliding frame 36 is respectively meshed and rotatably connected with the auxiliary rotating gear disc 38 at the upper and lower ends of the main rotating gear disc 37, and the surfaces of the main rotating gear disc 37 and the two sets of auxiliary rotating gear discs 38 are fixedly installed with inclined scrapers 39. A double-axis motor 310 is arranged at the center of the side of the vertical frame 31 through the machine base, and single-axis gear rollers 311 are fixedly installed at the front and rear ends of the double-axis motor 310. The two sets of single-axis gear rollers 311 are staggered and meshed with the corresponding double-axis gear rollers 34 respectively;

[0036] When clearing the tunnel, the crawler chassis 1 moves along the tunnel, and the two sets of hollow sliding frames 36 are close to the two side walls of the tunnel respectively, and then the double-axis motor 310 is started to drive the two sets of single-axis gear rollers 311 to rotate, and respectively mesh with the two sets of double-axis gear rollers 34 to realize the rotation of the two sets of double-axis gear rollers 34, and the end shafts of the double-axis gear rollers 34 drive the corresponding main rotating gear discs 37 to rotate, and each set of main rotating gear discs 37 is respectively meshed with the auxiliary rotating gear discs 38 at its upper and lower ends to realize rotation;

[0037] Therefore, multiple sets of toothed discs 38 rotate simultaneously and use the rotating inclined scraper 39 to scrape and remove the loose and easily falling soil or stones on the tunnel wall, thereby reducing the continuous falling of broken stones and soil during subsequent tunnel construction, keeping the tunnel surface smooth, and improving the efficiency of tunnel hazard removal.

[0038] Example 2: Please refer to Figure 3 and Figure 4 As shown, an adjustment assembly 33 is commonly provided between the two groups of long rods 32, and the adjustment assembly 33 includes two groups of convex discs 331, which are respectively fixedly installed at the center of the side of the two groups of long rods 32, and the convex discs 331 penetrate and are slidably connected to the inside of the slide grooves provided at the side walls of the vertical frame 31, and the centers of the two groups of convex discs 331 are respectively hinged with inclined hinge rods 332, and the tops of the two groups of hinge rods 332 are cross-hinged and movably connected with a push rod 333, and the top of the push rod 333 is provided with a cylinder 334 through a push rod, and the cylinder 334 is provided at the side wall of the vertical frame 31 through a machine base;

[0039] The spacing between the two sets of hollow sliding frames 36 is adjusted according to the width of the tunnel in the construction area. First, the cylinder 334 is started to use the push rod to push the push rod 333 to sink downward, and the bottom of the push rod 333 presses the top hinged ends of the two sets of hinge rods 332 together, forcing the angles of the two sets of hinge rods 332 to expand. At the same time, the bottoms of the two sets of hinge rods 332 push the corresponding convex discs 331 to move, and the long rods 32 connected to the convex discs 331 move accordingly. The spacing between the two sets of long rods 32 increases, and the double-axis gear rollers 34 and the hollow sliding frame 36 are pushed to move respectively, so that the main rotating gear disc 37 and the auxiliary rotating gear disc 38 on the surface of the hollow sliding frame 36 are closer to the tunnel wall, further improving the efficiency of tunnel wall repair and risk removal;

[0040] It is worth noting that the double-axis gear roller 34 and the single-axis gear roller 311 are set to be relatively long, and the front and rear teeth of the two are staggered and meshed, so the movement of the single-axis gear roller 311 will not cause movement obstruction.

[0041] Embodiment 3: After the inner wall of the tunnel is cleared of crushed soil and stones, the soil layer in the area where some stones fall off is easy to loosen and increase the risk of continuous falling off. Therefore, a compacting mechanism 4 is provided to further compact the trimmed wall surface to reduce the continuous falling of crushed stones and soil, and further improve the efficiency of tunnel risk removal construction;

[0042] See also Figure 3 , Figure 5 - Figure 7 As shown, a compacting mechanism 4 is arranged inside the top frame 2 adjacent to the trimming mechanism 3, the trimming mechanism 3 cooperates with the compacting mechanism 4, the compacting mechanism 4 comprises a second vertical frame 41, the second vertical frame 41 is fixedly mounted on the inner wall of the bottom of the top frame 2 and located on one side of the first vertical frame 31, and sliding shafts 42 are respectively arranged through the center of the front and rear ends of the second vertical frame 41, and the ends of the two sets of sliding shafts 42 away from each other extend to the outside of the second vertical frame 41 and are rotatably connected to the slave transmission wheel 43, and a connecting rod is commonly connected between one side of the sliding shaft 42 and the corresponding long rod 32, and a transmission belt is commonly sleeved between the slave transmission wheel 43 and the adjacent main transmission wheel 35;

[0043] The two groups of ends of the transmission wheels 43 away from the sliding shaft 42 are fixedly mounted with convex rotating cylinders 44, and the inner wall of the convex rotating cylinder 44 is provided with a limiting groove 45, which is composed of a plurality of groups of inclined grooves and a plurality of groups of transverse grooves, and the inclined grooves are arranged between two adjacent groups of transverse grooves;

[0044] The compacting mechanism 4 also includes two groups of pressing frames 46 slidably connected inside the top frame 2 and located at the front and rear ends. The upper and lower ends of the opposite surfaces of the two groups of pressing frames 46 are respectively connected to the opposite surfaces of the second vertical frame 41 through fixedly installed T-shaped sliding rods 47, and the outside of the T-shaped sliding rods 47 is provided with a spring group ring 471 in the through groove of the second vertical frame 41. The centers of the opposite surfaces of the two groups of pressing frames 46 are fixedly connected with plug posts 48, and the bottom surface of the plug posts 48 and one end of the convex rotating cylinder 44 are fixedly installed with a round shaft 49, and the round shaft 49 is slidably connected to the end of one group of inclined grooves;

[0045] After the slope of the inner wall of the tunnel is trimmed, the tamping mechanism 4 is used to compact the tunnel wall in sequence. The tamping mechanism 4 is operated with the help of the trimming mechanism 3. During the rotation of the two sets of double-axis gear rollers 34, the two sets of main transmission wheels 35 rotate accordingly, and the transmission belt drives the two sets of slave transmission wheels 43 and the corresponding convex rotating drums 44 to rotate. Each set of convex rotating drums 44 rotates relative to the plug column 48, and the round shaft 49 slides relatively along the inside of the limit groove 45.

[0046] The round shaft 49 first slides along the inside of the inclined groove, and uses the inner wall of the inclined groove to continuously press the round shaft 49 to force the plug post 48 to push, and the pressing frame 46 connected to the plug post 48 moves accordingly and pushes to the outside of the top frame 2, while pulling the two groups of T-shaped slide bars 47 to move and compress the spring coil 471, until the round shaft 49 moves to the intersection of the inclined groove and the transverse groove, the pressing force is lost, and the plug post 48 and the pressing frame 46 are forced to return to move under the resilience of the spring coil 471;

[0047] This is repeated to achieve the left-right reciprocating motion of the pressing frame 46, and intermittently press the walls on both sides of the tunnel respectively, to assist in compacting and compacting the repaired tunnel wall, improve the flatness of the tunnel wall, and further reduce the risk of continuous falling of broken soil and gravel in the tunnel during continuous excavation;

[0048] It is worth mentioning that when the spacing between the two groups of hollow sliding frames 36 is adjusted, the positions of the two groups of pressing frames 46 are also adjusted accordingly. The specific adjustment process includes: when the two groups of long rods 32 are pushed out, the two groups of connecting rods are used to pull the corresponding sliding shafts 42 to move. After the two groups of sliding shafts 42 are pushed out from the inside of the vertical frame 41, they push the corresponding slave transmission wheels 43, convex rotating cylinders 44, plug columns 48 and pressing frames 46 to move synchronously. The two groups of pressing frames 46 move away from each other and approach the inner wall of the tunnel respectively, so as to make adaptive adjustments according to the internal width of the tunnel.

[0049] In summary, when clearing the inside of the excavated tunnel, the crawler chassis 1 moves along the inside of the tunnel, and adjusts the spacing between the two sets of hollow sliding frames 36 according to the tunnel width of the construction area, until the two sets of hollow sliding frames 36 are close to the two side walls of the tunnel respectively;

[0050] Then, the double-axis motor 310 is started to drive the two sets of single-axis gear rollers 311 to rotate, and respectively mesh with the two sets of double-axis gear rollers 34 to realize the rotation of the two sets of double-axis gear rollers 34, and the end shafts of the double-axis gear rollers 34 drive the corresponding main rotating gear discs 37 to rotate, and each set of main rotating gear discs 37 respectively mesh with the auxiliary rotating gear discs 38 at the upper and lower ends thereof to realize rotation. Therefore, multiple sets of gear discs 38 rotate simultaneously and use the rotating inclined scraper 39 to scrape and remove the loose soil or stones on the tunnel wall;

[0051] At the same time, the tamping mechanism 4 is used to compact the tunnel wall in sequence. The tamping mechanism 4 is operated with the help of the finishing mechanism 3. During the rotation of the two sets of double-axis gear rollers 34, the two sets of main transmission wheels 35 rotate accordingly, and the transmission belt drives the two sets of slave transmission wheels 43 and the corresponding convex rotating drums 44 to rotate. Each set of convex rotating drums 44 rotates relative to the plug column 48, and the round shaft 49 slides relatively along the inside of the limit groove 45.

[0052] The round shaft 49 first slides along the inside of the inclined groove, and uses the inner wall of the inclined groove to continuously press the round shaft 49 to force the plug post 48 to push, and the pressing frame 46 connected to the plug post 48 moves accordingly and pushes to the outside of the top frame 2, while pulling the two groups of T-shaped slide bars 47 to move and compress the spring coil 471, until the round shaft 49 moves to the intersection of the inclined groove and the transverse groove, the pressing force is lost, and the plug post 48 and the pressing frame 46 are forced to return to move under the resilience of the spring coil 471;

[0053] This process is repeated to achieve left and right reciprocating motion of the pressing frame 46, and intermittently presses the walls on both sides of the tunnel respectively, to assist in compacting the repaired tunnel walls, improve the flatness of the tunnel walls, and further reduce the risk of continuous falling of broken soil and rocks during continuous excavation of the tunnel.
